The Rydberg atom-based device could be a fraction the size of existing antennae ...

Scientists have tracked an intense radio signal coming from deep in space to its origin – and been left shocked by what they found. For years, researchers have been looking to explain fast radio ...

New research suggests that alien radio signals may be transformed by plasma from their home stars — and scientists on Earth could thus be overlooking prime evidence of alien intelligence.

How can radio astronomers successfully identify extraterrestrial radio signals while discerning them from Earth-based radio signals? This is what a recent study published in The Astronomical Journal ...

The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more ...

The recent spate of unidentified drone sightings in the U.S., including some near sensitive locations such as airports and military installations, has caused significant public concern. Some of this ...
